Every city in the US has zoning codes. These codes outline how a space can be used. For example, doctors often think they can lease space in any office building; however most medical buildings have additional parking requirements to accommodate their staff and clients and traditional office buildings may not have enough parking to accommodate this use. Therefore, the tenant shouldn’t lease the space. These laws cover a large range of rules and, regulations, and the procedures to request a change in a facility’s zoning are usually quite complex and time-consuming.
